Best Masterpiece Grimlock?

I have been almost accidentally collecting Grimlock toys recently because he’s my favourite character but I don’t yet have a Masterpiece one. It seems like the Masterpiece has had a few releases with different decos and accessories. What is the best if I only want to get one? I wouldn’t say money is no object but I’m willing to wait to find the right one.

No shade to those who are but I’m not interested in knock-offs or third party alternatives.
